ABSTRACT
The chapter describes the characteristics of mud snails found in mud flats. The animal most closely associated with a mud flat community, especially near the low-tide line, is the eastern mud snail or Illyanassa obsoletus. Illyanassa belongs to the large group of animals called mollusks. Mud snails are nimble, possessing an agility not generally seen in snails. They are deposit feeders, which means that they feed on microscopic plant plankton. Their diet is especially rich in those phytoplankton called diatoms. Because mud snails feed on plant material, they are called herbivores. They graze by using their radulae to gather diatoms and other microscopic plants that cover the soft mud. Grazers such as these feed near the base of the food chain, and through metabolic processes, they convert living plant material into living snail tissue and energy. For this reason they are called primary consumers.
